IMPROVEMENT 1N SPINNING-mennen.

no'schedule-refen'ed to in these Letter atent and part: of the sans.

To all whom it mel/y concern.- Be it known that I, JOHN SPEIoHT,-of Bradford, in the county of York, and Kingdom of England, have invented new and useful Improvements in Machinery or Apparatus for Spinning, Twisting, and Roving Worsted, or other Fibrous Substances, to facilitate the doflng and I do hereby declare' that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to" the letters of reference marked thereon; that is 4to's'ay- This invention relates to that class of machinery or apparatus for spinning, twisting, or roving', known as throstle-rames and cap-frames; and

My improvements consist in the employment of dui plicate spindles or bobbin-studs, that is, in having two sets of spindles or studs, ,so arranged, that while one, setis in position for spinning, twisting, and roving, the.

other set is in position for doiiing- Each set, according to one method, isl mounted on a shaft capable of'turning on its axis,.and also of sliding endwise, such shafts being placed and operated so as that each set of spindles or studs may change positions alternately, or as and when required or other methods may be adopted of applying duplicate spindles or studs. 'In' carrying out this invention, I either employ fliers,

suspended, by their necks, toa rail, over the spindles l or studs, in which they are capable of rotating; orA I use whorles or whirls, constructed so as to be capable ot rotating in bearings formed in the lifter-rails, and traversed upand down thereby.

A guide-eye is fixed in each whorle or whirl, and a central hole js formed therein,of suiiicient diameter to allow the bobbin, when filled with the spun or twisted yarn, to pass through it.

When employing iiiers, I form a cup cr cavity over or in, each nier-neck, `to fit a suspending boss or socket attached to the rail, and to contain oil' or other lubricant. l l

y In orderthat this invention may beclearlyunderstood, I herein give reference to an accompanying sheet of drawings of an ordinary worsted-spinning frame, with my improvements applied thereto.

I,Description of the Drawings.

Figure 1 is a front elevation, and

Figure 2 is an end elevation-of the same.

In these drawings, I have the application of fliers specially constructed for carrying out this invention,

These iiiers, marked 0, are suspended, by their necks, to a rail, D, iix'ed to the ordinary top rail of the frame E. v v

One set or series of4 the spindles or bobbin-studs F is iixed on a shaft, F, which is4 mounted `in brackets F2, attached to the ordinary lifter-rail G.

Another set or series of spindles 01' bobbin-studs, H, is, in likcmanner, fixed to another shaft, H', which is also mounted in the said brackets F2..

VThese shaftsare geared together by spur-wheels, and are coupled by a double collar or link, I. 'A lever-handle, J, is iiXed on the shaft' F1, which passes through an oblique slot-hole in a plate,-K, fixed to the frame.

The set of studs F is shown with the tubes a, and spools therein, and in proper position for the spinningprocess, and for-the yarn to be wound upon them, by the fliers, iu the'usual manner, while the other set, H, is'shown without the bobbins, and placed out of' posi. tion for the spinning-process, but in a suitable position to have the full bobbins doiied or removed therefrom, and empty bobbins placed thereon, ready for thespinning and winding the spun yarn u on them;

It will be readily seen that, if the lever-handle J be pressed downward, it will move in the slot, and thereby turn both the shafts Fl and H' in opposite directions to each other, and also move them endwise, so y that the two sets of studs will change psitions or places, or that the studs F will be removed, for spinning and winding the spun yarn on thebobbins, but into position for doiiing, and that, simultaneously therewith,

the studs H will be placed in position for spinning and winding the spun yarn on the bobbins. r

Rotary motion-is communicated to the iiiers from an ordinaryroller, L,`rby straps -or bands, L, acting on pulleys or whirls, L2; fixed or formed on the vfliers.

The tubes a, on which the spools or bobbins i are placed, have 'rotary motion given to them by frict bnal contact with a strap, M, which is mounted on p leys vfixed on upright shafts, Ml and M2, the former of which shafts' being driven by a belt from a roller, N. i

. Figure 3 is a full-sized sectional view of' th flier,

and the rail in which it is suspended and rotates, howing its peculiar construction, and the method of suspension, andthe provision made for the lubrication thereof;A and also the bobbin-studs and their shafts,

one of said studs having a spool-bobbin thereon, in

proper form.

In this figure, c represents the tube of the ier, having a cup or cavity, d, to receive the boss or socket e, which is suspended from or attached to the rail.

The whirl f is screwed or secured to this cup, and serves to hold the flier, so that itandthe whirl may both be sustained by and yet .be free to rotate upon the boss, as shown, suitable openings, g, in the boss permitting the lubricating-material introduced between the tube and boss to lpass through the latter, and thus to lnbricate also the bearing-surfaces between the boss and the whirl and cup.

Figures 4 and 5 show, full size, the construction and method of applying whorles or whirls to be used instead of vliiers.

P is the said whorle or whirl, and l Q, the rail in which it is suspended, and in which it is rotating, the hole in the whirl being oi'- suitable diameter to allow the spool, whenlfull of yarn, to pass 2. The combination of the iers C, suspended by their necks, and constructed substantially as set forth, with the means for lubricating the same, substantially as shown and described.

JOHN SPEIGHT.

through it, the tweezles p carrying the yarn around the bobbins in the same manner as iiers do.

What I claim as my invention, and desire to secure by Letters latent, is

l. Two sets of spindles or bobbin-studs, F and H, arranged, respectively, upon parallel shafts, geared together and actuated substantially as described, so that, while one set is in position for spinning, the other set is in position for dofng.
